Formation of Acetyl CoA Pyruvate produced by glycolysis (see above) enters the mitochondrion and is converted to acetyl CoA by the reaction below. The remainder of the reactions of cellular respiration occur in the mitochondrion . pyruvate (C 3 ) acetyl CoA (C 2 ) + CO 2 During this step, NADH is produced from NAD + + 2H (oxidation). This step must occur twice for each glucose molecule because each glucose molecule produces two pyruvate molecules in glycolysis (above). The two-carbon compound produced is attached to Coenzyme A to produce acetyl CoA.

Unformatted text preview: Krebs Cycle The Krebs cycle can be summarized by either of the diagrams below. The diagram below occurs twice, once for each acetyl CoA. When acetyl CoA attaches to a C 4 molecule in the Krebs cycle, the Coenzyme A is released. Two acetyl CoA molecules are consumed to produce 4 CO 2 , 2ATP, 6 NADH and 2 FADH 2 . The ATP molecules are produced by substrate-level phosphorylation. The diagram below also summarizes the Krebs Cycle....
